Method Details

getFieldName
Description copied from interface:IndexFieldDataThe field name. -
getValuesSourceType
Description copied from interface:IndexFieldDataThe ValuesSourceType of the underlying data. It's possible for fields that use the same IndexFieldData implementation to have different ValuesSourceTypes, such as in the case of Longs and Dates. -
sortRequiresCustomComparator
protected boolean sortRequiresCustomComparator()Description copied from class:IndexNumericFieldDataShould sorting use a custom comparator source vs. rely on a LuceneSortField. Using a LuceneSortFieldwhen possible is important because index sorting cannot be configured with a custom comparator, and because it gives better performance by dynamically pruning irrelevant hits. On the other hand, LuceneSortFields are less flexible and make stronger assumptions about how the data is indexed. Therefore, they cannot be used in all cases.- Specified by:
